TMP03/TMP04 is a temperature sensor produced by Analog Devices. It features low power consumption, small size, and low cost. It can work in the temperature range of -40℃ to +150℃, and is suitable for various temperature measurement applications.
The document describes the TMP03 and TMP04 as monolithic temperature detectors that generate a modulated serial digital output proportional to temperature. These devices utilize an onboard sensor and a precision digital modulator to provide accurate readings independent of clock drift errors common in other modulation techniques.
Key features include low power consumption, flexible open-collector or CMOS/TTL-compatible outputs, and operation over a wide supply voltage range from 4.5 V to 7 V. The sensors are available in TO-92, SO-8, and TSSOP packages and are specified for operation from -40°C to +100°C.
| Accuracy (Typical) | ±1.5°C from –25 °C to +100 °C |
|---|---|
| Operating Temperature Range | -40°C to +100°C |
| Supply Voltage Range | 4.5 V to 7 V |
| Maximum Power Consumption | 6.5 mW at 5 V |
| Supply Current (Unloaded) | < 1.3 mA at 5 V |
The devices are available in TO-92, SO-8, and TSSOP-8 surface mount packages.
The output is a square wave where Temperature (°C) = 235 - 400 × (T1/T2).
No, the TMP03 has an open-collector output capable of sinking 5 mA, while the TMP04 offers CMOS/TTL-compatible output.
